Integral de $$$\frac{\sin{\left(x \right)}}{x}$$$

Halla $$$\int \frac{\sin{\left(x \right)}}{x}\, dx$$$.

Esta integral (Integral seno) no tiene una forma cerrada:

$${\color{red}{\int{\frac{\sin{\left(x \right)}}{x} d x}}} = {\color{red}{\operatorname{Si}{\left(x \right)}}}$$

Por lo tanto,

$$\int{\frac{\sin{\left(x \right)}}{x} d x} = \operatorname{Si}{\left(x \right)}$$

Añade la constante de integración:

$$\int{\frac{\sin{\left(x \right)}}{x} d x} = \operatorname{Si}{\left(x \right)}+C$$

$$$\int \frac{\sin{\left(x \right)}}{x}\, dx = \operatorname{Si}{\left(x \right)} + C$$$A
